Abstract: 209,384. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. fiir Elektrische Gl³hlampen). Jan. 5, 1923, [Convention date]. Soldering. - The leading-in wires of electric lamps, vacuum tubes, rectifiere, &c., are soldered to the caps during the operation of hardening the cement fillings thereof, so that the one application of heat serves for both purposes. As described in connection with screw-cap lamps, the caps after being secured to the bulbs 2 by cement are mounted in pockets in a revolving frame 1, each pocket being provided with an electric heating- coil 5. A metal cap 6 is placed over each lamp cap to distribute the heat between the thimble 8 and the central plate 9 to which the wires are to be soldered respectively. The ends of the wires are brought through aligned notches in the members 8, 9 so that by the aid of a pointer on the frame 1 the lamps can be readily positioned with respect to the solder-feeding appliances. For soldering the central wire, a wire 35 of solder is drawn from a reel 34 and passed between feedrollers 32, 33 mounted in a frame 40 adapted to be reciprocated vertically by a lever 42. When the frame and an attached feed tube 44 are lowered to feed the solder wire to the cap, the roller 32 is turned bv a ratchet-wheel 38 and a pawl 39. The second leading-in wire is soldered to the hot thimble by applying a solder wire 15 to it by mechanism similar to that described above, the frame 16 and the feed tube 27 being reciprocated by a cord 28 and a spring 19.

Title: Synchronising-pulse separator circuits
IPC: H04N5/16
Filed: 1975-04-18
Abstract: 1497604 Television systems SONY CORP 18 April 1975 [19 April 1974] 16118/75 Heading H4F A sync. pulse separator includes a circuit for adjusting the D.C. level of a video signal. The circuit includes a comparator which compares the signal with a fixed reference potential, the comparator output controlling a unit which has a fixed time constant and which adjusts the D.C. level via a feedback loop. The adjusted video signal is fed to a second comparator which delivers constant amplitude sync. pulses. In the embodiment disclosed a video signal SV applied at input 1 is inverted and passed via TR2 to output 5 and to comparator 6. A reference potential (ER) is applied to the comparator via a potential divider 8-10. When the signal level is less than the reference potential a capacitor 13 charges towards a fixed voltage applied at 3. The capacitor potential is added to the video signal SV by way of a feedback loop comprising TR5, TR6. If the level of the sync. pulse exceeds the reference potential TR3 becomes conductive so causing capacitor 13 to start to discharge. Consequently the D.C. level of the video signal is reduced until the signal no longer exceeds the reference potential. In order to separate the sync. pulses from the signal at output 5, the signal is passed to a circuit comprising TR7, TR8. Transistor TR7 is fed with a second reference potential (ES) which is a little less than that (ER) at TR4, being taken from the junction of resistors 9 and 10. When the level of the signal at 5 exceeds the second reference potential, as it does during each sync. pulse, a pulse appears at output 17, the pulses so generated all having the same amplitude.

Abstract: 452,334. Fuel pumps. SECK, W., 3, Paulsbornerstrasse, Halensee, Berlin. June 4, 1935, No. 16150. Convention date, June 4, 1934. [Class 102 (i)] [See also Groups XXXV and XXXVII] A diaphragm pump is actuated by a reciprocating electric motor comprising an electromagnet and an armature a secured to the diaphragm. The delivery stroke is effected by the spring f and is limited by contact between the nut m<1> and the casing p. The spindle s is guided by flat springs l, l<1> secured to the spindle and the casing. A sleeve b surrounds the core k and is of non- magnetic material and directs the lines of force to the auxiliary armature h. The interruptcr comprises a contact c<1> mounted upon a spring plate u, shaped as in Fig. 3, which is secured to the casing by screws passing through the holes s<1>, s<2>. The projection d upon the spindle s engages the end u<1> of the plate u and causes the end u<2> and the contact c<1> to move in opposite directions about some axis situated between them. The other contact c is carried by a spring plate h<1> secured to the casing and also carrying the auxiliary armature h. When the contacts c, c<1> engage, the armature h is attracted and moves downwards and carries with it contacts c, c<1> and lifts the end u<1> from the projection d. The period of contact is thus lengthened. When the projection d engages the end u<1> the contact is broken and the contact c is raised and during downward movement of the spindle s, the contact c<1> follows the contact c until it engages it. The period of break is thus lengthened.

Title: Improvements in or relating to the preparation of organo-siloxane polymers
IPC: C08G77/00
Filed: 1947-06-20
Abstract: An organo-bromo-silane or -chlorosilane is reacted with a substantially anhydrous tertiary alcohol to produce organo siloxane polymers.  A silicon tetrahalide may also be admixed with the organo-halosilane.  The relative molecular proportions may be varied; the tertiary alcohol may be in excess and the reaction conducted under reflux so as to remove hydrogen halide, and tertiary alkyl halide eventually distilled from the polymer, or the tertiary alcohol may be in restricted amount and the reaction conducted under such conditions, e.g. in a closed reactor, or at lower temperature, as to produce a polymer retaining some halogen atoms.  In the latter instance, the product may be subjected to further hydrolysis and condensation to produce higher polymers. Any of the lower polymers may be further polymerized as by blowing with air at an elevated temperature.  Tertiary butyl or tertiary amyl alcohol are the preferred alcohols and a specific list of exemplary organo-halosilanes includes various organo mono-, di- and tri-halosilanes such as methyl trichlorosilane, dimethyl dichlorosilane, octyl trichlorosilane, triphenyl bromosilane, di(octadecyl) dichlorosilane, naphthyl trichlorosilane, and others. In examples, reaction was effected between tertiary butyl alcohol and (1) diethyl dichlorosilane, to give a polymer mixture which on distillation gave 4 fractions of the apparent composition hexaethyl cyclotrisiloxane; octaethyl cyclotetrasiloxane; decaethyl cyclopentasiloxane; high boiling polymers; (2) ethyl trichlorosilane, under conditions to give an oil having 22 per cent by weight of hydrolysable chlorine; (3) phenyl ethyl dichlorosilane; (5) phenyl trichlorosilane; (6) a mixture of ethyl trichlorosilane and phenyl ethyl dichlorosilane to give a polymer containing chlorine; (7) isopropyl trichlorosilane; (8) ethyl trichlorosilane and ethyl phenyl dichlorosilane, the two chlorine-containing polymers being admixed and treated with further tertiary butyl alcohol; and (5) tertiary amyl alcohol was reacted with ethyl phenyl dichlorosilane.

Abstract: 530,380. Prepayment meters. SANGAMO WESTON, Ltd., and WESTON, G. E. June 6, 1939, No. 16593. Addition to 492,649. [Class 27] A prepayment mechanism of the kind in which the insertion of a coin closes an electric circuit has a coin pocket 21 the surrounding wall surfaces of which are electrically insulating. The outer coin slot 14 is inclined, and is located at the back of a stationary housing 12 of insulating material and fitted with a door 10 the opening of which causes the pocket 21 to slide into a position in. which a similarly inclined slot 27 therein aligns with the slot 14. The coin on entering the pocket falls astride the slots to prevent insertion of a fresh coin, and closing of the door 10 allows the pocket 21 to return forward under spring action till the coin, sliding along an insulating platform 30, falls over the edge thereof into a coin receptacle 34. This has a rear contact plate 39 and a swinging base and side 36, 36a of conducting material, the coin bridging the two. An abutment member has a double-width gap to receive thin and thick coins and to take the slots 20 and 27 out of alignment if a too-thick coin or several thin coins are forcibly inserted, these being automatically freed as the pocket moves forward. A cam-operated pivoted block is brought to bear against the coin by a spring, the size of the coin determining which of a series of interrupted gear teeth shall be brought into engagement with a sprocket on a crediting shaft, and when more than one coin is inserted the effective coin diameter is that of the largest coin. A non-conductive coin remains in the coin receptacle 34 until the next conducting coin is inserted, and is then discharged into a returned coins chute or the like. Movement of the coin pocket 21 during this action is prevented by an armature attracted to the operating motor when this is energized. An indicator flag 380 on a shaft 123 gives a visual indication at an aperture 381 as to whether the apparatus is ready for coin insertion.
